ttcn3-docker-run.sh: Use interface "up" flag, not operstate 

Don't use the "operstate" sysfs attribute to determine if an interface
is "up", use the actual UP-flag (0x01) in the "flags" sysfs attribute.

The "operstate" attribute may at least occasionally be "unknown" and
remain in that state (causing jenkins jobs to wait indefinitely), while
the flags (which we don't look at before this patch) indicates it is "up".

This is a fixup to the below commit:
